Verdict
The clearest difference is rating: KnowWake at 4.1 against Manatee Alert's 2.3. KnowWake also leads on ratings volume (250 vs 11) and update cadence (every 11 days vs monthly). Manatee Alert's advantage is iOS requirement (7.0 vs 13.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
KnowWake holds the better App Store score, 4.1 against 2.3. That said, the two scores are not equally well evidenced: KnowWake has 250 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 57% of Manatee Alert's written reviews are positive against 55% of KnowWake's, so the app with the better star average is not the one people write more warmly about.
Manatee Alert ships an update monthly, KnowWake every 11 days. The most recent releases landed on September 28, 2026 and October 13, 2026 respectively.
